Tune and verification of control system algorithms for offshore installation operations involving complex and advanced machinery and difficult due to its safety factor. It may be also very costly or even impossible to establish certain test conditions in the physical process environment of the control system. To solve this problem, the Hardware-In-the-Loop-Simulation (HILS) can be regarded as an effective method for testing the control system prior to its final development. The sophisticated HILS is composed of a control system and a HIL simulator which is a simulation model of the offshore plant developed by software. In this study, we focus on the application of HILS for a heave compensator which is used to keep the position or the lowing speed of a lifting object. This study contains three components. Firstly, a physics-based analysis component is used to develop a simulation model of an offshore plant, that is, a HIL simulator. Secondly, the programmable logic controller (PLC) component, that is a control system, is used to regulate the offshore plant model, including a proportional-integral-derivative (PID) feedback controller which aims to control the position or lowering speed of the lifting object. Thirdly, an interface component is developed to communicate the data between the HIL simulator and the control system in real-time. To evaluate the applicability of HILS for a heave compensator, it was applied to an example of an offshore support vessel (OSV) crane. In order to verify the control system for the crane operation in case of heave stabilization of the lifting object, two simulation processes had been established with both a software PLC (software-in-the-loop) and a hardware PLC (hardware-in-the-loop). HILS makes it possible to test the heave compensator without building costly prototypes and without endangering natural environment.

This paper introduces a testing mothod about hydroturbine governing system based on dSPACE hardware-in-the-loop-simulation. PID parameters are adjusted by hardware-in-the-loop -simulation. The results of the simulation show that it can provide simple, intuitive simulation model, and make parameters adjusting more intuitive and easier. The validity of the testing platform have been testified by the results of real-time simulation and hardware-in-the-loop-simulation. The superiority of controldesk in the real-time simulation is prominent.

Simulation Results

Information about vehicle dynamics states is indispensable for modern dynamics control system on vehicle today. For economic reasons, a technique called “virtual sensor” which bases on dynamical model of vehicle and an observation algorithm are used to estimate real states of vehicle. In this paper, a system based on Hardware-in-the-loop simulation will be used to estimate the vehicle states in real time. CarSim is a professional software for simulating the dynamics of vehicle which is used as a virtual vehicle in this paper. An observer based on Luen-berge method is developed and implemented by Arduino Mega 2560 board. Matlab/Simulink plays the role of acquistion and data transfer center. The simulation results show the good performance of observer in real time condtion when the estimated values are well converged to real values given by CarSim.

This paper describes the development of a distributed network system for real-time model based control of industrial gas turbine engines. Distributed control systems contribute toward improvements in performance, testability, control system maintainability and overall life-cycle cost. The goal of this programme was to offer a modular platform for improved model based control system. Hence, another important aspect of this programme was real-time implementation of non-linear aero-thermal gas turbine models on a dedicated hardware platform. Two typical applications of real-time engine models, namely hardware-in-the-loop simulations and on-line co-simulations, have been considered in this programme. Hardware-in-the-loop platform has been proposed as a transitional architecture, which should lead towards a fully distributed on-line model based control system. Distributed control system architecture offers the possibility of integrating a real-time on-line engine model embedded within a dedicated hardware platform. Real-time executing models use engine operating conditions to generate expected values for measured and non-measured engine parameters. These virtual measurements can be used for the development of model based control methods, which can contribute towards improvements in engine stability, performance and life management. As an illustration of model based control concept, the example of gas turbine transient over-temperature protection is presented in this study.

Hil Simulation

This paper presents the performance of shutdown system one (SDS1) implemented on a programmable logic controller (PLC) within real-time hardware-in-the-loop (HIL) simulation. SDS1 evaluation is focused on steam generator (SG) level low trip scenarios. A comparison of the findings with simulated expected plant operation is performed. An Invensys Triconex Tricon v9 safety PLC is interfaced to a real-time nuclear power plant (NPP) simulation suite (DarlSIM), replicating the operation of the Darlington NPP SDS1. Design basis accidents (DBA) associated with SDS1 regulatory standards are developed and applied to the two simulation environments. HIL simulation is a preferred method for testing systems prior to installation and is necessary to ensure proper SDS verification and validation. The performance of the Tricon v9 PLC, the HIL simulation platform and the two simulation environments are evaluated.
